If an authority is the owner
or operator of a housing project that includes units for persons of other than
low or moderate income, the operating expenses of that project (or of all such
projects, together, owned or operated by the authority) shall be met entirely
from rents from the project (or projects) together with any rent subsidies
provided to low income tenants in the project (or projects). No rent
subsidy may be provided to any tenant who is not a person of low income, and no
rent subsidy may be paid from bond proceeds. (1987, c. 464, s. 4.)
